Lisbon's Oceanarium is one of the world's largest aquariums. Designed by American architect Peter Chemeyeff, it rises from the river and is reached by footbridge. It is a deep-sea diving experience without any of the risks, with about 25,000 fish, seabirds, and mammals in an enormous central tank that is the size of four Olympic-sized swimming pools.
